Works excellent
By tmanners
Excellent product, works exactly as discribed. Threads hold well, and take moderate force to remove, compared to no loctite.
Loctites:
Blue = removable
Red = almost permanent
Green = permanent/never remove

Works Great as always
By S. Mathew
When it comes to accessories that bolt on to weapons, one should always apply loctite to the screw attachments. I've used loctite blue over the years on multiple rifles, mg's etc. and none have ever had any issues despite heavy firing schedules. I would not hesitate to buy again.

Good price and Quick Ship
By J. Tsai
Purchased this for several uses. One for a screw-type pin on a 1911 sight that always wiggled loose after 100-ish rounds. Haven't had an issue since. Also have used it on other projects around the house and has worked every time. Please note that the blue is the "non-permanent" type and red is the "permanent" one. Make sure you choose the correct type for your application. Sometimes the blue does take quite a bit of wrestling to get it to shear though. Also, the Loctite is very runny, so I would highly suggest laying down some newspaper or pouring in a little cup or plastic ramekin and use a q-tip or toothpick to get on threads.
